There’s a nationwide shortage of 2mg Ozempic. My patient can’t actually get it, despite the fact he has bad diabetes and a heart condition. But everyone wants it because “everyone” on TikTok tells us that it’s the greatest thing for losing weight. They’re probably right because nearly everyone who is significantly overweight has a measure of diabetes/prediabetes and semaglutide (the generic name of Ozempic and Wegovy) is probably the best choice for those folks, especially in light of being overweight. And since 75% of Americans are overweight, “everyone” is pretty close. NOW, what they DON’T tell you is that once you go off the drug, and you haven’t significantly changed all the other inputs (food, activity, sleep, stress), then all that weight will come back on. It might take a little longer than it took to get rid of it, but it’ll be back…and then what? Actually --- we don’t know. It’s possible that you end up about the same as before you took it, but it might be that you end up worse than before you started (won’t go into the possible mechanisms). OH – let’s not forget the side effects – a good percentage of patients get nausea, vomiting, diarrhea, constipation (yeah, your GI system gets messed with) and fatigue. A smaller percentage gets pancreatitis, gall bladder problems and potentially serious eye issues, which can be really bad.
Another issue of no justice in American healthcare. I forgot to mention that the drug isn’t covered by insurance for non-diabetics and it’s very expensive. It’s actually not much cheaper than liposuction….

Scientists caution that for weight loss, the diabetes medication’s long-term safety and efficacy aren’t settled. That hasn’t stopped influencers.
Billionaire Elon Musk credited it for his dramatic weight loss. Celebrity sites allege that many more A-listers are using it to stay trim. And TikTok is full of influencers showing off their startling before-and-after shots showing off their weight loss after using it.
What is it? A medication called semaglutide, which is sold under different brand names, including Ozempic, approved in 2017 for treating type 2 diabetes, and Wegovy, approved just last year for weight loss.
The buzz about these drugs has created a shortage of both, according to the U.S. Food and Drug Administration, which is expected to last for several months—causing alarm among patients with diabetes who rely on Ozempic to help control their blood sugar. Experts caution that it’s important to understand these are not miracle drugs—and that there are risks to taking them outside of their intended use.
Here’s what you need to know about semaglutide, including how it works and the risks.
What’s the science behind the drug?
Semaglutide helps lower blood sugar by mimicking a hormone that’s naturally secreted when food is consumed, says Ariana Chao, assistant professor at the University of Pennsylvania School of Nursing and medical director at the school’s Center for Weight and Eating Disorders. This medication, administered through injection, helps people feel full for longer, helps regulate appetite, and reduces hunger and cravings.
There is significant demand for the drug. In 2019, more than 11 percent of the population was diagnosed with diabetes, while more than four in ten adults classified as obese in 2020.
Patients with type 2 diabetes often have impairments in insulin, a hormone that helps break down food and convert it into fuel the body can use, Chao says. Semaglutide signals the pancreas to create more insulin and also lowers glucagon, which helps control blood sugar levels. This can result in weight loss but experts point out that Ozempic has not been approved for that purpose, though semaglutide at a higher dose (Wegovy) has been.
Wegovy is the first drug since 2014 to be approved for chronic weight management. The difference between the two drugs is that Wegovy is administered at a higher dose of semaglutide than Ozempic. Wegovy’s clinical trials showed more weight loss but only slightly greater improvements in glycemic control compared to Ozempic, Chao says.
The FDA sees Ozempic and Wegovy as two different medications for different uses. Chao says many insurance companies cover Ozempic for diabetes but don't cover Wegovy for obesity—a prime example of weight bias in health care. That's why some medical providers use the two doses somewhat interchangeably, as obesity and type 2 diabetes are inextricably linked–obesity is the leading risk factor for developing type 2 diabetes.
What are the risks?
Like every medication, there can be downsides.
The most common side effects are gastrointestinal issues, such as nausea, constipation, and diarrhea, Chao says—and more rarely, pancreatitis, gallbladder disease, and diabetic retinopathy.
These drugs have been extensively studied, but their relatively recent approval means researchers still don’t know what the effects of taking them long term might be.
Continuing research is helping us understand more about what happens when people stop taking these medications—which many may be forced to do amid current shortages. Research does suggest that stopping use of this medication could cause patients to regain weight, especially if they didn’t make any lifestyle changes.
“In almost all weight-loss studies, it really depends on your foundation,” says Stanford endocrinologist Sun Kim. “Your efforts at lifestyle will determine how much weight you lose. If you have your foundations like food, exercise, and sleep, you’re gonna do well.” If not, you might regain as much as 20 percent of the weight lost per year.
These medications can also be incredibly expensive, especially without insurance. Kim says an injection pen can run more than $1,000.
What does it mean to use this drug off-label?
Using a drug off-label means using it in a way other than its intended and its FDA-approved purpose, which may not be safe or effective. Ozempic has been approved only for type 2 diabetics, and Wegovy has been approved only for patients with a BMI above 30, or 27 if they have a weight-related comorbidity like high blood pressure.
“There is no scientific evidence to show whether this medication will be effective or of benefit to those who do not fit the criteria from the FDA-approved label indications, such as people with a BMI lower than 27,” Chao says. “We also do not know the side effects or risks in these populations—there could be unknown drug reactions. These medications are not meant to be a quick fix.”
Even if you meet the criteria, experts warn against trying to obtain the medication without a prescription by traveling to countries that don't require them.
“When the medication’s not used under supervision of a health-care provider, then they can come into misuse,” Chao says. “There could be more serious adverse events that can happen.”
Other experts also argue that, with Ozempic becoming hard to find, diabetes patients should be the first in line.
“What I do worry about, and I hope it's only temporary, is the supply chain issue,” Kim says. “If I had to triage and prioritize, I would maybe favor someone that is controlling their diabetes to get it.”
Robert Gabbay, the American Diabetes Association’s chief scientific and medical officer, says the organization is “very much concerned” about the Ozempic shortage.
“The medication has been an important tool for people with diabetes,” he says. “Not only does it lower blood glucose and weight but it has been shown to decrease cardiovascular events—heart attacks—one of the leading causes of death for those living with diabetes.”
A last resort?
Still, Kim says that prescribing drugs like Ozempic and Wegovy to patients who are desperate for a new approach to weight loss can make her feel “like a superhero.” By the time patients come to her, they’ve often tried methods like Weight Watchers and following the advice of dieticians. In that case, she says, medications like Ozempic and Wegovy can be a great option.
“What I find is sometimes as they're becoming successful at losing weight, it really does feed into their lifestyle too, and then they're able to be more active,” Kim says. “It’s hard to lose weight. Seventy-five percent of the U.S. population is overweight or obese. I feel that we shouldn't be holding this back if this can help.”
Chao agrees that these medications are a good alternative for those who are unable to lose 5 percent of their body weight within about three months of making lifestyle changes. Still, she recommends trying those approaches before turning to medication.
Patients should “make sure that they're focusing on a healthy dietary pattern, reducing calories, as well as increasing physical activity,” she says. “It’s important they know that even if they are taking the medication, it's not an easy way out: They're still going to have to make lifestyle changes.”
